Who must know that the cars in their train have received proper inspection?

The conductor is responsible for the overall safety and operational integrity of the train, which includes ensuring that all equipment, such as cars, have undergone proper inspection before the train departs. This knowledge is crucial because the conductor must be aware of the condition of the train to make informed decisions that prioritize safety and compliance with regulations. It's part of the conductor's duties to communicate with the crew about the train's status, manage any issues that arise, and ensure that all safety protocols are followed. Proper inspections are vital for preventing accidents or equipment failures during transit, making this knowledge fundamental to the conductor's role in maintaining a safe operation.
